BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phalaenopsis plant, botanically known as Phalaenopsis hybrida, and hereinafter referred to by the name ‘Moonlight Serenade’.

The new Phalaenopsis plant is a product of a planned breeding program conducted by the Inventor in De Lier and Heemskerk, The Netherlands. The objective of the breeding program is to develop new fast-growing and freely flowering Phalaenopsis plants with good leaf shape and large flowers with unique and attractive patterns and coloration.

The new Phalaenopsis plant originated from a cross-pollination in July, 2012 in Nantou, Taiwan of Phalaenopsis hybrida ‘Timothy Christopher’, not patented, as the female, or seed, parent with Phalaenopsis hybrida ‘Sogo Yukidian’ X ‘Yu Pin Firework’, not patented, as the male, or pollen, parent. The new Phalaenopsis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Heemskerk, The Netherlands in December, 2017.

Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since December, 2018 has shown that the unique features of this new Phalaenopsis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Phalaenopsis have been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Moonlight Serenade’. These characteristics in combination distinguish ‘Moonlight Serenade’ as a new and distinct Phalaenopsis plant:

-   -   1. Upright plant habit.     -   2. Moderately vigorous growth habit.     -   3. Strong flowering stems.     -   4. Strong leaves.     -   5. Freely flowering habit with typically two inflorescences per         plant, each inflorescence with numerous flowers.     -   6. Flowers with fused labella, typically referred to as a “big         lip” type.     -   7. White-colored flowers with a large white-colored labella with         light purple-colored stripes and marbling.     -   8. Good postproduction longevity.

Plants of the new Phalaenopsis can be compared to plants of the female parent, ‘Timothy Christopher’. Plants of the new Phalaenopsis differ primarily from plants of ‘Timothy Christopher’ in plant habit and flower size as plants of the new Phalaenopsis are taller and have broader flowers than plants of ‘Timothy Christopher’ are dark yellow in color with only a few spots and no dashes or stripes. In addition, the labellum lateral and central lobes are fused in plants of the new Phalaenopsis whereas the lateral and central lobes of the labellum of plants of ‘Timothy Christopher’ are not fused.

Plants of the new Phalaenopsis can be compared to plants of the male parent, ‘Sogo Yukidan’ X ‘Yu Pin Firework’. Plants of the new Phalaenopsis differ primarily from plants of ‘Sogo Yukidan’ X ‘Yu Pin Firework’ in flower color as flower labella of plants of the new Phalaenopsis are white in color with light purple-colored stripes and marbling whereas flower labella of plants of ‘Sogo Yukidan’ X ‘Yu Pin Firework’ are solid white in color without any stripes or marbling.

Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘Pillow Talk’, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Pillow Talk’ in flower color as flower labella of plants of the new Phalaenopsis are white in color with light purple-colored stripes and marbling whereas flower labella of plants of ‘Pillow Talk’ are white in color with only a few stripes and no marbling.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Phalaenopsis plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phalaenopsis plant.

The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘Moonlight Serenade’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flower of ‘Moonlight Serenade’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 10.5-cm containers in a glass-covered greenhouse in Heemskerk, The Netherlands and under cultural practices typically used in commercial Phalaenopsis production. Plants were 18 months old when the photographs and description were taken. During the first twelve months of production of the plants, day and night temperatures averaged 27° C. During the final six months of production of the plants, day temperatures ranged from 20° C. to 22° C. and night temperatures ranged from 18° C. to 20° C. During the 18 months of production, light levels ranged from a minimum of 5,000 lux to a maximum of 10,000 lux. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
